exprprofvar - Calculate variance of gene expression profiles

Syntax

Variance = exprprofvar(Data) exprprofvar(..., 'PropertyName', PropertyValue,...) exprprofvar(..., 'ShowHist', ShowHistValue)

Arguments

`Data`	Matrix where each row corresponds to a gene.
`ShowHistValue`	Property to control the display of a histogram with variance data. Enter either `true` or `false` (default).

Description

Variance = exprprofvar(Data) calculates the variance of each expression profile in a data set (Data). If you do not specify output arguments, this function displays a histogram bar plot of the range.

exprprofvar(..., 'PropertyName', PropertyValue,...) defines optional properties using property name/value pairs.

exprprofvar(..., 'ShowHist', ShowHistValue), when ShowHist is true, displays a histogram of the range data .

Examples

Calculate the variance of expression profiles for yeast data as gene expression changes during the metabolic shift from fermentation to respiration.

load yeastdata
datavar = exprprofvar(yeastvalues,'ShowHist',true);
